To all whom it may concern:

Be it known that we, ALBERT E. (look and THOMAS VAN TUYL, citizens of the United States, and residents of the city of Evanston, 1n the county of Cook and State of Illinois, and the city of Kankakee, in the county of Kankakee and State oflllinois, respectively; have invented certain new and useful improvements in an Oscillating Axle Mechanism; and we do hereby declare that the fol-- lowing is a full, clear, and exact description of the same, reference'being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a .part of this specification.

,This' invention pertains to an improved type of a vehicle chassis having a straight line drive connected with a transmission-and differential which are securely mounted on the chassis frame and are adapted to transinit a drive to the chassis driving wheels which are mounted to oscillate about the chassis rear axle housing and receive a drive from the rear axle. v l It is an Ob ect of thisinvention to provide an automobile chassis with oscillating axles adapted to removably receive the chassis driving wheels which are connected to receive a drivesfrom the chassis rear axle.

It is also an object of this invention to provide a vehicle chassis wherein the rear rivmg wheels are spring suspended and adapted to oscillate with respect. to the chassis driving axle; I

It is a furt er object of the invention to prbv'ide an oscillating axle upon which a driving wheel is adapted to be removab1y mounted to receive a drive from a driving axle about which the wheel supporting axle oscillates Another object of the invention is to con struct a chassis driving mechanism wherein a rear axle housing has a bracket pivotally mounted thereon for supporting a stud shaft on which a driving wheel-is removably mounted in position to be driven through speed reducing gears from the rear driving axle in said rear axle housing.

It is. furthermore an object ofthe inven-" tion to provide a shock absorbing spring mechanism for a wheel supporting axle I L7 which-is mounted to oscillateabout a driving axle geared with a wheel on said oscillating axle. I

It is a furtherobject of this inventiontto:

I Specification of Lettens ratent. Patented May 30,1922 Application filed May 14, 1920. Serial K0. 381345. i

provide a chassis wherein a direct driven" transmission and differential are secured on the chassis frame to transmit a reduced drive through a driving axle geared with a Wheel removably supported on a stud shaft disposed parallel to the driving axle and adapt;

'ed to oscillate about the driving axle housi is another object of the invention to'prowhereby the driving wheels of a vehicle are,

adapted to be remov ably supported on auxiliary axles which are supported by spring suspended brackets journalled on a driving axle housing to permit the auxiliary axles to oscillate about the driving axle.

.Other and further important objects of this invention will be apparent from the disclosures in the specification and drawhe invention (in a. preferred form)- is illustrated in the drawings and hereinafter more fully described.

On, the drawings:

Figure 1 is a fragmentary plan view of a telescoping vehicle chassis equipped w1th an oscillating wheel supporting axle mechan sm embodying the principles of thls invention.

Figure 2 is a fragmentary side elevation thereof. 7

Figure 3 is an enlarged view of a'drlvlng wheel taken on line 3-3 of Figure 1.

'Figure 4 is a'fragmentary section taken on line 4-.4 of Figure 3 showing parts 1n elevation. a

Figure 5 is an enlarged detail section taken on line 55 of Figure 2.

Figure 6 is a side elevatlon of a modified form of aspring-suspension mechanisr'ufor I the chassis.

As shown on the drawings The reference numeral 1- indicates a longi- I tudinally adjustable telescoping chassis frame having a front axle 2 and front-wheels 3 adjustable with the front section of the.

chassis frame. A telescoping drive shaft 4 has one end thereof connected with the vehicle motor and the other and directly connected with a gear transmission -5 and a differential 6. Transverse rods 7 and 8 are supported across the rear portion of the chassis frame by means of brackets or supports 9 through which the ends of said rods project.- The transmission 5 and the differential 6 are rigidly securedto the chassis frame and to the, transverse rod 7.

Secured to the projecting ends of the rods 7 and 8 on each side of the chassis frame are the lower ends of links 10 to the upper ends of which the ends of a leaf spring 11 are pivotally connected. ('lamped or secured. around the middle portion of the spring 11 is a clamp. 12, the under side of which is provided with a rack 13.

The. differential housing has integrally formed on the end thereof a rear axle sleeve or jack shaft housing 14 having apertured lugs 15 integrally formed thereon to permit the housing to be rigidly secured tothe chassis frame or vehicle body. Disposed longitudinally within the axle housing 14 is a jack shaft ordriving axle 16, the inner end of which isconnected with the differential to receive a drive therefrom. The outer endof the main axle 16 projects out-of the axle grally formedon the bracket '21 parallel to the sleeve 19-is a bearing sleeve 22 adapted to receive one end of an auxiliary or countershaft 23, which is parallel to the, axle 16.

Mounted on the outer projecting-end of the counter-shaft 23, is a roller bearing 24" and a ball bearing 25 for rotata-bly supporting a chassis rear driving wheel26. An internal gear 27 is formed on the wheel 26 and is inmesh with thepinion 18 of the axle 16.

The "internal gear 27 is enclosed within an oil tight drum or casihg28, which is, secured 29 which meshes-with on the spring '11.

In the modified formof the devicetshown in Figure 6, the construction is substantially v with a plate 31 forming'a part of a clamp 32 engaged around the middle portion of the spring 11. Y ,7

The operation is as follows:

With the telescoping frame arrangement shown in Figure 1 a straight line drive from the vehicle engine is transmitted through the telescoping shaft 4 directly to the transmission 5 and the differential 6. The trans- 13 of which mesh with the gear segments 29,

which are secured 'on the brackets 21. The supporting links 10 for the springs permit said springs to shift or move with changes in the'load so that at different loads the hearing points of the springs on the gear seg ments 29 change. The novel spring suspension permits easy riding qualities to be ob- {angled with light loads as well as with heavy The wlistance of the auxiliary shafts 23 with respect to the frame 1 is variable since .the supporting brackets 21 are adapted to swing or oscillate on the stationary jack shaft housings 14. The springs act as shock absorbers and prevent shocks from being transmitted to the vehicle driving mechanisms.

In the modified form ofthe device shown in Figure 6 the cam 30 co-acts with the shoe or plate 31 mounted on the spring. A rolling action or contact is obtained between the members 30. and 31, and the slippage is slight.

'The driving gaged on the shaft 23 and due to the gearing 1827 between the axle.16 and said Wheels a reduced speed is transmitted from -the vehicle driving mechanism to the vehicle driving wheels.

We are aware that numerous details of wheels 26 are removably en-- construction may be varied through a wide purpose limiting the patent granted other- ,wise than necessitated by the prior art. to the outer end of the bracket 21.
